A sorority sister from a college campus in Dallas is suing the Greek organization's national leaders who she says tried manipulating her with a secretly-made recording of the group's members dancing unclothed.

FOX's Eben Brown reports:

A member of Kappa Kappa Gamma at Southern Methodist University, in Dallas, is filing a million dollar lawsuit against the sorority's national leadership, who she says bullied her and fellow sisters by threatening to release a video of them singing to the incoming pledges dressed only in underwear and after having alcohol to drink.

The suing sorority sister says the house mom used security cameras to record it, but without getting permission, and now copies are spreading around. National Kappa has already kicked out 18 sisters for their alleged involvement.
